I\'ve been looking at these pace issues for decades now. Even though I believe I have some unique insights, IMO there are no accurate formulas for these kinds of things. There are general tendencies that can be formulized, but horses are individuals with varying degrees of stamina, brilliance, overall ability etc... As a result they are impacted differently by these pace and surface issues.
IMO, the trick is to look at the final time figure. If if doesn\'t make sense relative to the horse\'s typical performance, \"very often\" a close examination of pace and/or surface tendencies reveals a possible or even probable explanation.
Artificial track paces tend to fall somewhere between traditional dirt and turf paces. So I would guess it\'s likely there is some compression of figures, but not nearly as large as we see on turf.
Also, I am not entirely convinced that the relationships between distances are nearly as uniform as many people think on the different surfaces or even on the same surface depending on how fast/speed favoring/slow/tiring the track is.
